Publication number: 20250114415Abstract: A method for lowering cholesterol and lipid levels using the Antrodia cinnamomea water-insoluble dietary fiber prepared as herein. After ethanol and water extraction, Antrodia cinnamomea wastes are dried and superfine-comminuted to obtain Antrodia cinnamomea waste powder. The waste powder treated with NaOH solution containing NaBH4 is extracted it twice to obtain two extracts. The two extracts are combined and an appropriate amount of glacial acetic acid are added for neutralization. The extracts are centrifugalized and precipitate is collected. After washing the precipitate with ultrapure water, the precipitate is dissolved with LiCl-DMSO. The precipitate that is insoluble in the LiCl-DMSO solution is dialyzed and freeze-dried to obtain the water-insoluble dietary fiber component ACA-IDK of Antrodia cinnamomea. The LiCl-DMSO solution is subjected to ethanol/DMSO fractional precipitation, and then the precipitate is collected and dialyzed.Type: ApplicationFiled: December 20, 2024Publication date: April 10, 2025Inventors: LIANZHONG AI, YONGJUN XIA, PENG MENG, HUI ZHANG, GUANGQIANG WANG, ZHIQIANG XIONG, XIN SONG

Patent number: 10920229Abstract: The present invention relates to a method for improving the heterologous synthesis of a polyketide by E. coli and use thereof. The yield of the polyketide heterologously synthesized by E. coli is significantly increased by attenuating the expression of seventy-two genes, such as sucC and talB, in a host strain, wherein the highest yield increase rate can reach 60% or more. Currently, erythromycin is the most clear model compound in the study on the biosynthesis of polyketids. The production strain of the present invention enables massive accumulation of 6-deoxyerythronolide (6-dEB), an erythromycin precursor, in the fermentation process, laying the foundation for the industrial production of the heterologous synthesis of erythromycin by E. coli.Type: GrantFiled: May 18, 2015Date of Patent: February 16, 2021Assignee: CAS Center for Excellence in Molecular Plant SciencesInventors: Yong Wang, Zhiqiang Xiong, Shujie Song, Qiaoxia Liu, Jianfeng Wang
